f1.Y In an internalcombustion engine, the combination Vof a dependingcylinder head having an upstanding inner wall, said wall forming `withthe head outer wall an an# nular cooling spac.ea tubular membersurrounding said'inner wall in spaced relation thereto, said tubularmember having its lower end open and inl communication with the coolingspace, and means for introducing water between said member and the innerA.wall ofthe head.

V.2..InV an internal combustionvengine, the combination of a dependinghead having an annular water space therein, a tubular memberk securedtoV said head vertically dividing said V,Wat'erspace, said tubularmember having its bottom end open, and means forming an opening throughsaid tubular member adjacent the upper .end thereof. j

3. In an 'internal combustionengine, the combination of a depending headhaving an annular -water space, a tubular partition eX- tendingdownwardly within said space in spaced relation to both inner and outerwalls thereof whereby said space is divided into yannular passageways,means forming communication between said passageways adjacent the bottomof the annular space, and means for introducing Vwater within one ofisaid passage ways.

4. In an internal combustion lengine the. combination of a dependingcylinder'head having inner and outer walls forming an annular waterspace, a vertical tubular partition, within'said space'terminatingadjacent the bottom thereof, means for introducing water on one side ofsaid partition, and means for causing the water on one side of thepartition to flow' downwardly toward the bottom of said annular space.

511In an internal combustion engine, the combination of a dependingcylinder head having inner and outer tubular walls forming an annularwater space therebetween, a'

tubular partition intermediate said walls in 'y' spaced relationythereto, means forming a passagewayv between opposite sides of thepartition at the lower end thereof, means forming a passageway throughthe partition atthe upper end thereof, and means for causing water toflow through one passageway and along one side of the partition in onedirection, and along the other side of the partition in the oppositedirection.

6. In an internal combustion engine the combination of a dependingcylinder head having inner and router,A walls forming an annular waterspace within the head, a tubular v'deflector forming a verticalpartition within said annular space, said deiiector having an inturnedflange at its upper end in contact with the inner walls of the head, thelower portion of said deflector being spaced from both the inner andouter walls of the head, means forming a communication between oppositesides of said deiector adjacent the bottom of the space, and meansforming a waterconduit in communication with the interiorofsaiddeflector below the inturned flange. Y Y Y 7 In anrmternalcombustion engine the combination 'of a depending cylinder headv havingconcentric inner and outer walls forming anan-nular water space, atubular deflector surrounding the inner lwalls in spaced relationVthereto and projecting down within the space adjacent the bottomthereof,

means forming a closure between the deflector and the vinner wall,Ameans forming a water conduit to the space between the deflector andinner wall, and means forming a passage between opposite sides Yof saiddeliector adjaf cent the bottom of the water space.

8.'In an'internal combustion engine, combination of a cylinder having awater jacket, a cylinder head closing'the upper end circling said.extension in spaced relation' thereto, and means for producingwaterfiow between saiddetlector and extension.

9. -In an internal combustion engine, the'- combination Iof acylinderhaving a water jacket, al cylinder head closing thevupper end of saidcylinder,a cover over said cylinder and head enclosing a water` space incommunication with the water'jacket, said 7 head having outerV walls and`a tubular eX- tensionV projecting'fupwardly through said cover, saidextensionv forming with the side walls an annular water space, aitubular deiiector encircling said extension in spaced TIL relationthereto, means forming a closure for the upper end of the space betweenthe deflector and extension, said deflector having its lower end -open,'and'y means forV directing water through the deflector adjacent theupper endthereof. i

10. In an internal combustion engine, the combination of al cylinderhaving a water jacket, a cylinder head closing-the upper end of saidcylinder, a` cover Vover said cylinder the 'and head enclosing a Waterspace in communication with the water jacket, said head having outerWalls and a tubular extension projecting upwardly through said cover,said extension forming with the side walls an annular water space1 atubular deflector encircling said extension in spaced relation thereto,means forming a closure for the upper end of the space between thedefiector and extension, said deector having its lower end open, andmeans comprising a conduit passing through the cover for directing waterthrough the delector adjacent the upper end Y thereof.

In testimony whereof, I aiix my signature.
